O( n ) of the 100 element array, where "n" is the item location index.

Explanation:

From the meaning of the word "sequential", the definition of this algorithm should be defined. Sequential donotes a continuously increasing value or event, like numbers, increasing by one in an arithmetic progression.

A list in programming is a mutable data structure that holds data in indexed locations, which can be accessed linearly or randomly. To sequentially access a location in a list, the algorithm starts from the first item and searches to the required indexed location of the search, the big-O notation is O( n ), where n is the index location of the item searched.

Answer:

(c) A list of words

Explanation:

First let's format the code properly

fin = open('words.txt')

for line in fin:

     word = line.strip()

     print(word)

Second, let's explain each line of the code

Line 1:

The open() function is a built-in function that takes in, as argument, the name of a file, and returns a file object that can be used to read the file.

In this case, the name of the file is words.txt. Therefore, the variable fin is a file object which contains the content of the file - words.txt

Line 2:

The for loop is used to read in each line of the content of the file object (fin).

Line 3:

Each line of the contents is stripped to remove any trailing and leading white spaces by calling on the strip() function. The result of the strip is stored in the variable word.

Line 4:

The content of word at each of the cycles of the loop is printed to the console.

Therefore,  the overall output of the program is a list of words where each word represents a line in the target file (words.txt)

The program is an illustration of string manipulations.

word represents (e) A string with no newline

The program is given as:

fin = open('words.txt')

for line in fin:

        word = line.strip()

        print(word)

On line 3 of the program, the variable word contains the value of the string line, after the new lines and trailing spaces have been removed from the variable line.

This means that: variable word is a string with no newline

Explanation:

FCC is the abbreviation for The Federal Communications Commission (United States Federal Communication Commission). It is, as a rule, an administrative area. It is a free Federal administrative office of the United States government dependable straightforwardly to Congress, built up by the Communications Act and made by resolution to manage interstate and worldwide interchanges by radio, TV, wire, satellite, and link. It includes an investigation on pending changes in the remote world.

FCC certainly has consequences for the present status of 5 GHz Bridging Spectrum. As far as possible one of the U-NII groups which can be utilized outside with the 5.725-5.825 band which is perfect fitting open air tasks. The 2.4 GHz ISM band might be utilized outside where the yield power at the purposeful radiator can't surpass 1 watt. In the United States, the FCC manages the frequencies utilized, the yield power levels, and the open air utilization restrictions.

There is an effect of the FCC 5 GHz U-NII report and a request on Wi-Fi Networks. FCC's activities are to change some specialized principles for the 5 GHz U-NII groups. The specialized change that is affirmed is - U-NII 1 band (5.150 - 5.250 GHz) indoor activity limitation being evacuated permitting utilization of the band for open air hotspots, WISPs, and scaffold joins. There will be a development of open hotspots profiting by this change. The FCC considers 11 channels under the Operating Frequencies.

The FCC has characterized UNII-2 and UNII-3 groups, the two of which had four channels. The channels were divided 20 MHz separated with a RF range data transmission of 20 MHz giving non-covering channels utilizing 20 MHz channel width.

The UNII-2 band was assigned additionally for open air tasks and allowed outside recieving wires. The UNII-3 band was proposed for open air connect items and allowed outer radio wires, however the UNII-3 band is likewise utilized for outside 802.11a/n/air conditioning WLANs.

FCC (America) underpins Operating Frequency Range for 802.11b and 802.11g on Center Frequency: 2412, 2417, 2422, 2427, 2432, 2437, 2442, 2447, 2452, 2457, 2462. FCC has delivered an amendment to the guidelines covering the 5 GHz 802.11a channel utilization. This correction has included 11 extra channels, carrying the accessible channel's ability to 23 channels.

As far as possible your complete force yield by utilizing a sliding scale when you set up a significant distance Wi-Fi connect. The scale really begins at 30 dBm of enhancement power utilizing a 6 dBi directional reception apparatus. For each 1 dBm drop in enhancement power, there would be an expansion in the intensity of directional radio wire by 3 dBi. The FCC permits this sliding scale since when you utilize a bigger highlight point radio wire, your shaft example will cover less territory and cause less impedance for other people.

Explanation:

The above program first prompts the user to enter two numbers. Here the data type of two number is float in order to accept floating numbers. The switch statement contains cases which execute according to the choice of user. The choice available to user is: 1,2,3,4 and 5

If the user selects 1 then the case 1 executes which calls the method add. The method add takes two numbers as parameters, adds the two numbers and returns the result of the addition. This result is displayed on output screen. However if the result of addition is a negative number then the message: "Oops option 1 is returning the negative number that is:" is displayed on the screen along with the negative answer of that addition.

If the user selects 2 then the case 2 executes which calls the method sub. The method works same as add but instead of addition, sub method takes two numbers as parameters, subtracts them and returns the result of the subtraction.

If the user selects 3 then the case 3 executes which calls the method mul. The method mul takes two numbers as parameters, multiplies them and returns the result of the multiplication.

If the user selects 4 then the case 4 executes which calls the method div. The method div takes two numbers as parameters and checks if the denominator i.e. second number is 0. If its 0 then Division by 0 message is displayed along with result i.e. infinity. If second number is not 0 then method divides the numbers and returns the result of the division.

If the user selects 5 then the case 5 executes which calls the method average. The average method then  asks the user to enter two more numbers first2 and second2 and takes the sum of all four numbers i.e. first, second, first2 and second2. Then the result of sum is divided by 4 to compute average. The method returns the average of these four numbers.

Answer:

a) [00:05:00]

Explanation:

Timestamps are markers in a transcript which are used to represent when an event took place. Timestamps are in the format [HH:MM:SS] where HH is used to represent hour, MM to represent the minute and SS to represent the seconds. They are different types of timestamping such as:

i) Periodic time stamps: Occurs at a consistent frequency

ii) Paragraph time stamping: At the beginning of paragraphs

iii) Sentence time stamp: at the beginning of sentence

iv) Speaker time stamp: at change of speaker.

Since a part of 5-15 minutes with time-stamping (every 30 seconds), The time stamping should start at 5 minute [00:05:00] and end at [00:15:00]. This is a periodic time stamp since it occurs every 30 seconds, this means the next time stamp would be [00:05:30] and this continues until 15 minute [00:15:00]

Based on the information given, the time stamping will be A. [00:05:00]

It should be noted that timestamps simply mean the markers that we in a transcript that are used to represent when an event took place.

They are typically in the format [HH:MM:SS]. Therefore, if you are working on the part of 5-15 minutes, time-stamping (every 30 seconds) should start at 00:05:00.

Explanation:

Our technological world has become deeply dependent upon the continuous availability of electrical power. In most countries, commercial power is made available via nationwide grids, interconnecting numerous generating stations to the loads. The grid must supply basic national needs of residential, lighting, heating, refrigeration, air conditioning, and transportation as well as critical supply to governmental, industrial, financial, commercial, medical and communications communities. Commercial power literally enables today’s modern world to function at its busy pace. Sophisticated technology has reached deeply into our homes and careers, and with the advent of e-commerce is continually changing the way we interact with the rest of the world. Intelligent technology demands power that is free of interruption or disturbance. The consequences of large-scale power incidents are well documented. A recent study in the USA has shown that industrial and digital business firms are losing $45.7 billion per year due to power interruptions.1 Across all business sectors, an estimated $104 billion to $164 billion is lost due to interruptions with another $15 billion to $24 billion due to all other power quality problems. In industrial automatic processing, whole production lines can go out of control, creating hazardous situations for onsite personnel and expensive material waste. Loss of processing in a large financial corporation can cost thousands of unrecoverable dollars per minute of downtime, as well as many hours of recovery time to follow. Program and data corruption caused by a power interruption can create problems for software recovery operations that may take weeks to resolve. Many power problems originate in the commercial power grid, which, with its thousands of miles of transmission lines, is subject to weather conditions such as hurricanes, lightning storms, snow, ice, and flooding along with equipment failure, traffic accidents and major switching operations. Also, power problems affecting today’s technological equipment are often generated locally within a facility from any number of situations, such as local construction, heavy startup loads, faulty distribution components, and even typical background electrical noise

Answer:

Here is the C++ program:

#include <iostream> //to use input output functions

#include<string.h> // to manipulate strings

using namespace std; //to identify objects like cin cout

void ReverseString(char* original_str){ // function that reverses a C-string

       char* ptr1 = original_str;  // pointer that points to the start of C-string

       char* ptr2 = original_str; // pointer that points to the start of C-string initially

       for (int i = 0; i < strlen(original_str)- 1; i++) {//iterates through the length of the C-string

           ptr2++;} //moves ptr2 to the end of the C-string

       while(ptr1 < ptr2) {// swaps each character of C-string using pointers

               char temp = *ptr1; //declares a temp variable to hold character that *ptr1 points to

               *ptr1 = *ptr2;

               *ptr2 = temp;

               ptr1++; //increments ptr1 moving it forward

               ptr2--;   }} //decrements ptr2 moving it backwards

int main(){ //start of main() function

       char input_str[]="";  /// declare a C-string

       cout<<"Enter original string: "; //prompts user to enter a string

       cin>>input_str; // reads that C-string from user

       ReverseString(input_str); //calls function to revserse the input string

       cout<<"\nReversed string: "<<input_str;} // displays the reversed string

Explanation:

The program has a function ReverseString that takes a C-style string as parameter and reverses the string using pointers.

The ptr1 and ptr2 are pointers that initially point to the beginning of original string.

for (int i = 0; i < strlen(original_str)- 1; i++) this statement has a for loop that iterates through the original string and moves the ptr2 to point at the end or last character of the C-string. strlen() method is used to get the length of the C-string. At each iteration ptr2 moves one time forward until the last character of the C-string is reached.

while(ptr1 < ptr2) statement has a while loop that works as follows:

checks if ptr1 is less than ptr2. This evaluate to true because the index of first character that ptr1 points to is 0 and last character is 5 so 0<5. Hence the statements inside while loop execute which swaps the character of C-string from beginning and end index using ptr1 and ptr2. a temp variable is declated to hold character that *ptr1 points to.

For example

original_string = "xyz" Then temp = *ptr1; stores the character that *ptr1 points to i.e. 'x'

*ptr1 = *ptr2; This statement assigns the character that *ptr2 points to the *ptr1. Basically these pointers are used as indices to the C-string. So this means that the *ptr1 now stores the last character of the C-string that is pointed to by *ptr2. So *ptr1 = 'z'

*ptr2 = temp; This statement assigns the character that temp stores to the *ptr2. We know that temp contains the first character i.e 'x'. So *ptr2 = 'x'      

ptr1++; The ptr1 is incremented to 1. This means it moves one position ahead and now points to the second character of the C-string.

ptr2--; The ptr2 is decremented to 1. This means it moves one position backwards and now points to the second character of the C-string.

Now the while loop breaks because ptr1 < ptr2 condition evaluates to false.

So the original string is reversed using pointers. Hence the output is:

zyx

Answer:

c. 20

Explanation:

The program works as following:

x is initialized to 10

y is initialized to 30

if (x < 0) statement checks if the value of x is less than 0. This condition evaluates to false because x=10 so 10 is greater than 0. So the statement inside the body of this if condition will not execute. Hence the program control moves to the else if part:

else if (x < 10) statement checks if the value of x is less than 10. This condition evaluates to false because x=10 so x is equal to 10 and not less than 10. So the program control moves to the else part and the statement in else part executes:

else {

y = 20;

}

This statement in else part assigns the value 20 to y

Then the program control moves to the following statement:

cout << y;

This statement prints the value of y. As the else part assigns 20 to y so the output is:

20
